Yeah. One Piece has been consistantly good for a while now. In fact I can't remember a part of the manga that I didn't enjoy. Bleach is on it's way up, the latest flashback thing is really fleshing the story out a bit now, in between the constant fighting. Naruto, I was getting properly sick of, the story seemed to just be jumping around randomly without any feeling of importance. In the last few months there's been little or no break inbetween Jiraya dying, Itachi dying, and the story just generally being flipped on it's head. Seems to be slowing down and taking stock now though, which I like.
tl;dr: Bleach and Naruto are getting better, One Piece remains awesome.
